Abstract

Purpose: Description and analysis of the rare, but existing complications from the application of calcaneal lengthening osteotomy for treatment of the symptomatic flatfoot deformity in children and adolescents.

Materials and methods: The procedure of calcaneal lengthening osteotomy has been introduced at the University Orthopaedics Hospital „Prof. B. Boichev“in 1999. The study included 64 children or 92 cases, the average age being 11.61±1.90, and the youngest child being 7 years of age. The deformity is more often found in males, making up 44 or 68.75% of the cases. The females make up 20 of the cases, or more precisely 31.25%. We used angle X-ray measurements of the feet in AP and profile positioning, with a mandatory upright position of the pateints, to figure out the severity of the flatfoot deformity. When grading based on the subjective criteria, we used an instrument called Visual-Analogue-Scale Foot and Ankle (VAS FA). To grade the complications, we applied the clinically based Dindo-Clavien classification, used in orthopaedic surgery.

Results: The average timing for an overall follow-up for all cases is 18.65± 8.29 months. A correction of the CIA appears in all cases that were operated. The average value of the angles at the time of diagnosis of the deformity, the average value was 13.07°, which has risen to 23.25° by the last follow-up session. When analyzing the changes in the MA (angle of Meary), we observed that the angle has decreased to 7.87° in the last follow-up session. The TNCA has decreased with an average of -8.272±5.27°, taking into consideration the high statistical reliability (p≤0.00). Even though we mark five cases of dorsal subluxation of the distal fragment, we have observed a complication from a degenerative process of the CC (calcaneo-cuboid) joint.
